IMPROVEMENT IN LANTERNS.

Specification forming part of Letters Patent No. 32,161, dated April'23, 1861.

To all whom it may concern.-

Be it known that I, E. B. COFFIN, of J ohn ston, in the county ofProvidence and State of Rhode Island,-have invented a new and ImprovedLantern; and I do herebydeclare that the following is a full, clear, andexact description of the same, reference being had to the annexeddrawings, making a part of this specification, in which- 7 Figure 1 is avertical central section of my invention, taken in the line x m, Fig. 2;Fig. 2, a horizontal section of the same, taken in the line 3 3 Fig. 1.

.Similar letters of reference indicate corresponding parts in the twofigures.

The object of this invention is to obtain a lantern for burning keroseneor coal oil.

To enable those skilled in the art to fully understand and constructmyinvention, I will proceed to describe it.

A represents a glass globe, the lower part of which isfitted within abase, B, perforated at its side, as" shown at a, and encompassed by aperforated band, G, which forms a register to vadmit more or less airinto the lower part of the globe, as may be "desired.

' D represents the fountain or oil-reservoir of forated sides, asshownate, and a 'tnbe,f, runs centrally through compartment 6, to admit ofthe glass chimney F passing through into the upper compartment, 0, ofcylinder G, as shown clearly in Fig. 1. v

H is a horizontal deflector or plate, which is fitted in the uppercompartment, 0, of cylinder G. This plate is of circular form and ofsmaller diameter than the cylinder G, in order to allow a space, allaround between itsedge and the cylinder. The plate ordeflectorH isretained in proper position by elastic lugs or projections h,-whichextend from the edge of plate H and bear against the inner smalldome-shaped chamber, 1, the sides of which have, apertures'i in them.

7 J represents valves, which are simply metal plates bent in V form andfitted in slots over the apertures z, said'plates or valves beingallowed to swing freely in the sides. of the dome or chamber ,1. Thelower part of the dome or chamber I communicates with the upperapartment, 0, of cylinder G by perforationsj, and the lower part of thecompartment b of cylinder G communicates with the globe A byperforations k.

The wick may be raised and lowered by turning a small shaft, d, whichextends through the flange at the bottom of the fountain D, the upperpart of said haft being a serew, e'. which gears into a worm-wheel, f,on the end of the shaft 9-, which has the small wheels on it. thatengage with the wick. (See dotted lines in Fig. 1.)

From the above description it will be seen that the flame is suppliedwith air which passes through the perforations e of the compartment b ofcylinder G, the air passing down through. the perforationsk at thebottom of said compartment into the globe A, and thence through theperforations of the burner, the warm air passing up the chimney F andthrough the upper compartment, 0, ofcylinder G'into the chamber I, andout through the openings or apertures i. The valves J, inconnection withthe deflector H, prevent any back-draft, the valves closing on thewindward side of the dome or chamber 1-, and the supply of air to theflame is rendered very constant in consequence of its circuitous routeand the perforations through which itfpasses. The lower perforations maybe more or less opened, to admit the air in greater or lessquantity intothe lower part of the globe A, by regulating the register or band C, andin case of the'wind blowing strongly, so as to.

affect the flame, they may be nearly or entirely opened.

Having thus described my invention, what I claiin as new, and desire tosecure by Letters ranged substantially as and. fer the purpose.
